May I ask you, why you cannot run your Ranorex tests directly on iPad? I mean, what exactly do you want to achieve with webdriver/appium? Running web-based tests on iPad's Safari?

=> We managed to run the test case on iPad's RxBrowser. But the target is to run the test case on Safari browser and not on RxBrowser.

=> Yes. The goal is to run the web-based tests on iPad's Safari browser. Is it possible to achieve this from Windows machine with Ranorex 8.3.1. Can we achieve this without Mac?

=> On Ranorex forum they claim that test cases can be run on Native browsers(Including Safari). What do they really mean? It is possible only via Mac and Appium installed on it? And I read that Ranorex can not be installed on Mac? So somehow I need to connect Mac from Windows. OK. Assuming that Appium is set and running on Mac. Now how do I bring the script recorded from Ranorex on Windows to the Mac where Appium is running. How to run it on real iOS(iPad) device?

=> I am desperately looking for a step by step guide document to achieve this from Windows machine. I would highly appreciate it if you could help me with any guide document or any kind of hint is also highly welcomed

It should be possible to execute tests in Safari on iOS devices using Appium. From Ranorex you can connect to the Appium Server and trigger your tests.
So, generally you should first ensure you can reach your device and recognize elements with Appium itself.
Afterwards, you can bring in Ranorex.
As far as I know, Ranorex only supports connecting to your Appium server and as soon as you can automate a device with Appium itself, you should also be able to execute a test with Ranorex over Appium.

So, what you will have to do now:
1. Make sure that Appium itself works and you are able to connect to your device and recognize elements in a Safari browser.
2. Afterwards you can set up a new webdriver endpoint in Ranorex and connect to the up and running Appium Server
